Clean up AMD Fam14 SSDT

The old SSDT ACPI code would only include the AGESA or the coreboot SSDT. Now
include both. AGESA generates the Pstate SSDT and the second coreboot SSDT is
for TOM and TOM2. Now, generate the coreboot SSDT instead of patching it. This
fixes some ACPI errors in Linux and Windows bluescreens.

The Persimmon acpi_tables.c is where the main changes were made and then
replicated in the other Fam14 boards. Please test the other mainbords if you
have one.
